Cozy Timer is a free Android app developed by FLUX that helps users improve the quality of their sleep and extend the life of their device. It is a multimedia app that stops music or video playback after a set time, helping users fall asleep without worrying about prolonged playback, battery drain, or screen burn-in. With the app, users can easily set a timer for one hour and the playback will stop automatically.

Cozy Timer has recently been updated to version 3.0, which includes several new features, such as a simpler and clearer UI that lets users choose between a dark and light theme. The app also includes a do not disturb feature that turns on when the timer expires, as well as the ability to turn on/off WiFi (Android 9 or lower), Bluetooth, and do not disturb at specific times. In addition, the timer starts automatically when the set app is launched for a specific time (premium feature).
